We divide 66357860 by 603
We want to divide 66357860 by 603.

Moving on to step 1:
603 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 603

On to step 2:
603 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 603

On to step 3:
603 goes into 663 1 times with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 603 from 663, we get 60.
Include the next digit (5) from the dividend after 60, then repeat: 605 / 603

Advancing to step 4:
The number 603 fits into 605 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 603 away from 605, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 603

Advancing to step 5:
27 divided by 603 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtracting 0 from 27 leaves us with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 603

Going ahead to step 6:
603 can be fit into 278 0 times, resulting in a remainder of 278.
The number 0 becomes the next digit in our result. 
Result so far: 1100.0
Subtract 0 from 278 to get 278.
Fetch the next digit (6) from the dividend, attach it to 278 and continue: 2786 / 603

On to step 7:
If we divide 2786 by 603, we get 4 and a remainder of 374.
Use 4 as the next digit of our solution. 
Result so far: 11004.0
Deduct 2412 from 2786 and we're left with 374.
Bring next digit (0) of the dividend behind the 374 and repeat the process: 3740 / 603

Step 8:
603 can be fit into 3740 6 times, resulting in a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 110046.0
If we take 3618 away from 3740, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 9:
1220 divided by 603 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 110046.2
If we subtract 1206 from 1220, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 603, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 110046.2
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
The number 603 fits into 1400 2 times, leaving a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 110046.202
Subtract 1206 from 1400 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 12:
If we divide 1940 by 603, we get 3 and a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 110046.2023
If we subtract 1809 from 1940, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 13:
The number 603 fits into 1310 2 times, leaving a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 110046.20232
Subtract 1206 from 1310 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 14:
The number 603 fits into 1040 1 times, leaving a remainder of 437.
The next digit of our result is 1. 
Result so far: 110046.202321
Subtracting 603 from 1040 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 15:
If we divide 4370 by 603, we get 7 and a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 110046.2023217
If we take 4221 away from 4370, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 16:
603 goes into 1490 2 times with a remainder of 284.
The next digit of our result is 2. 
Result so far: 110046.20232172
Deduct 1206 from 1490 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 110046.20232172 with a balance of 2.84e-07.
